Hi all,
I try to understand alternatives to reification for Linked Data publishing,
since reification is discouraged. For example, how could I express the
following without reification:
@prefix dc: <http://purl.org/dc/elements/1.1/>.
@prefix foaf: <http://xmlns.com/foaf/0.1/>.
<http://ex.org/stmt>
rdfs:label "Statement that describes user interest in a document"@de;
rdf:subject <http://ex.org/User>;
rdf:predicate foaf:interest;
rdf:object <http://ex.org/Item>;
dc:publisher <http://ex.org/Service>;
dc:created "2010-10-13"^^xsd:date;
dc:license <http://ex.org/License>.
<http://ex.org/User> rdf:type foaf:Agent.
<http://ex.org/Item> rdf:type foaf:Document.
N3 quoted graphs are a nice approach..
@prefix dc: <http://purl.org/dc/elements/1.1/> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix : <http://ex.org/> .
{ :User foaf:interest :Item }
dc:created "2010-10-13"^^xsd:date;
rdfs:label "Statement that describes user interest in a document"@de;
dc:publisher :Service;
dc:created "2010-10-13"^^xsd:date;
dc:license :License .
This has the benefit of comprising only triples (no quads etc) and also
locks the description + statement together so that they can't vary
temporally.
Best,
